    First of all, thank you for your excellent work. I understand this if V1 and V2 are connected to the ends of R1 and R2 . The fact that two instruments are connected at A and B, confuses me. What does that mean? If we don't touch the connections and simply move V1 next to V2, what value will we measure? Will the value on the instrument change? Could this mean that we also measured the value induced in the wires we used to connect the instruments? Even in this case, your statement still holds. Thank you. I wish you all the best

      if we swing V1 over to the same side as V2 without cutting any cables then they will both show the same voltage. I suggest you also watch this video th-cam.com/video/wz_GqO-Urk4/w-d-xo.html

    Dear Dr. Walter Lewin, I am a Master's student in the Faculty of Physics, and this is largely thanks to you. You are the first person I ever saw who loves physics so deeply and sincerely. You inspire me immensely, it’s amazing to see someone so dedicated to their passion. I can't even count how many times I've rewatched your lectures and other videos-they always lift my spirits. You know, when studying became exhausting and I questioned why I was doing all of this, why I chose to study physics, I would think of you. I’d reread your book, and every time, I’d remember just how much I love physics and how much I want, like you, to share this love and inspire others. Thank you so much! Thank you for your support, your work, and your inspiration! You are incredible person and outstanding lecturer!

    Sort of like the news they say what they want to share and censored the rest that doesn’t complement what they’re trying to portray, but if you have a picture or video of what actually happened, it gives the reader more clear interpretation of what was going on during that time rather than going by hear say!

    Giotto was important because he made paintings look more realistic by adding depth and emotion. He focused on making people and scenes look natural, which was a big change from the flat, stylized art before him. His work helped inspire the Renaissance and influenced other artists to make their art more lifelike. I think he was trying to express what was actually occurring during that era rather then just going by what was told in the literature that we have of that time!

    Artist: Giotto Subject: Massacre of the Innocents Period: Italian Renaissance painting Created: 1304-1305 Matthew tells the story of the Massacre of the Innocents. King Herod ordered the killing of all boys under the age of two born in the Bethlehem area, for the Magi had told him that a child destined to become the king of the Jews had been born in the city. Jesus was saved from the massacre when his Family fled to Egypt.

      @@lecturesbywalterlewin.they9259 Hi Prof. I know you think I made a mistake with my formula but what I wrote is based on my SUFT formula and the new discoveries it. That stands for Super Unified Field Theory that's why it's different than Einstein's. Let me explain a little bit to you and it'll make more sense. The reason nobody has been able to do a Unified Field Theory is for one very big reason. The first thing They needed to do is Quantize Time and that turned out to be the Most Important piece in the Whole formula. Without that it just plain Can't be done and No way to Unify Quantum Mechanics and Relativity at least not properly!! Once that was done All the other pieces starting to fall into place like muons that have a life of a few seconds become stable. What started the quest for that turned out to be the original riddle regarding the speed of light. Why was it a riddle what happens to everything that gets close to the speed of light it slows down or stops which means light would also be affected. Unless something was altering that situation. It turned out to be Time because is not a light barrier it's that Time barrier for lack of a better term. The reason why Einstein's E= mc2 turned out to be another surprise, a major one and that was there is a timestamp on light. That's why his formula still worked. So the two are actually in a relationship that happened at the Big Bang and has been going on ever since. There was all kinds of surprises but like a large puzzle with no picture on the pieces they All still started to fall into place. I have sent e-mails to the people CERN, The Perimeter Institute, MIT And Multiple Other Universities trying to get it peer reviewed and feedback. I want to see if somebody can actually find flaws in this formula and I mean I want them to try and tear it apart and scrutinize it. Simply put if it's as strong as I know that it is it will stand up to anyone's rigorous examination and passed with flying colors. You did tell me to get it published in nature It needs to be peer reviewed first or they won't touch it and I don't blame them one bit so that's what I'm working on. Like you told me too many people have walked up to you and said I have this or I have that and it turned out to be Junk or Flawed or Both. Simply put I have no intentions of wasting anyone's time and I definitely am not going to waste my own either. I have other projects, I could have spent the time on. So right now I'm waiting to hear back from these different people and see what they say! I posted that for you cause I thought you might be curious to what I've been up to not to bug you. I will post you a comment when I hear back from any of them to let you know what they said if I am wasting their time or my own. I've heard people say that if a unified field theory is found, it would Wreck Physics. I believe it will just opened new doors for new discoveries and re-energize science. it will make it so scientist while proper data so they can make real discoveries in a major way. Don't get me wrong there are things in my formula about are hypothetical but they are testable and provable is far as I understand where science is right now. Thank you for getting back to me. John
